PRP/HSR is Enabling the Next Wave of IEC 61850 Substations
For mission-critical or time-sensitive applications, even millisecond long network interruptions cannot be tolerated, as they may severely impact system operation or jeopardize the safety of onsite personnel. The IEC 62439 standard states that the time that the plant allows for recovery before taking emergency actions (e.g., emergency shut-down, fall-back mode) should be less than 10 ms. In IEC 61850 edition 2, it also clearly states that the communication redundancy times of GOOSE and SMV protocols in substation automation systems are required to be BUMPLESS (i.e., have a zero switch-over time).

World’s First PRP/HSR Integrated Communication Computing Solution
Moxa has developed an integrated PRP/HSR redundancy box (RedBox) with Coupling & QuadBox and a native PRP/HSR rackmount computer as management server. These PRP/HSR substation solutions not only achieve bumpless recovery, but also help collect, analyze, and integrate raw data from various devices onto a single management platform, enabling efficient and visually represented PRP/HSR network management that makes network diagnosis, troubleshooting, and device condition monitoring easier than ever before.
